Bahamas weather in September is usually worse than normal for the year thanks to a higher risk of rain.

September historically is the worst weather month of the annual Caribbean hurricane season. It begins June 1 and ends Nov. 31, but over a 30-year period September has had the most rain, tropical storms and hurricanes.

The Bahamas and especially Nassau are a popular golf destination during spring months when temperatures are moderate and the risk of rain is low.

But tourism takes a steep dive in September and reaches the low point of the year, according to the Caribbean Tourism Organization. The high risk of rain and the potential for tropical storms and hurricanes keep away both cruise and overnight visitors.

Nassau Rainfall in September

The average total rainfall of 6.5 inches in September for Nassau is actually not as bad as the eight inches in June or nine inches in August, according to records from the Bahamas Department of Meteorology.

But it is still well above the average for the city and above many other Caribbean islands.

It rains 17 days during the month on average, the same number as July. August has the most rain days per month at 19.
